Steam is generated in the boiler of a cogeneration plant at 10 mpa and 450 degc at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa, and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through the condenser, which operates at 20 kpa. determine: a) the power produced and the rate at which process heat is supplied in this mode, and b) the power produced and the rate of process heat supplied if only 60% of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
